Читать книгу Introduction to Nanoscience and Nanotechnology - Chris Binns - Страница 26

In the previous chapter, the special properties of matter at nanoscale dimensions were presented and how this novel behavior could be exploited in technologies as diverse as advanced engineering materials and health care. This chapter is about nanoparticles and the environment, which encompasses naturally occurring nanoparticles and environmental applications of nanotechnology. Sections 2.1–2.7 discuss naturally occurring nanoparticles, both in our immediate environment, that is, the Earth's crust, oceans and atmosphere and out into deep space, where nanoparticles with their unique properties have helped shape the observable Universe. Section 2.7 describes the use of nanoparticles in addressing environmental issues via two important examples, that is, removing toxins from groundwater and recycling plastics.
